Hi, in column 24 I can see 6 at bottom, it produces 1 pixel. Then in the last column only one dark red is missing - all rows ending with black has background in that column.Column 34 - only black is missing, so you can eliminate some rows.

Take a look at my screenshot. I put red blocks on the clues in row 24 and in column 25. In clumn 25 there is a black 3, but when you look at the clues in row 24, you will see that after the black 1 you have in then grid, there should go a sequence of brown 1,2. That means that the red spot I marked in the grid has to be background. Now you can continue in column 25 where you can place 1 block of the black 3
